Connects the IC697 PLC to a LAN The is a member of the family of IC651 Factory LAN hardware and software products. The Factory LAN family of products provides high performance solutions for interconnecting automation controllers and for integrating them into multi-vendor networks. The plugs into a single slot in an IC697 PLC rack and provides an standard 15-pin D-connector for attachment of a user-supplied AUI (Attachment Unit Interface) or transceiver cable. The AUI cable connects to a user-supplied transceiver that is directly connected to the 10Μbps Ethernet network cable. The transceiver must be compatible and must have the SQE option enabled. Transceivers are commercially available to operate on a variety of 10Μbps media including thickwire coaxial cable (10Base5), ThinWire coaxial cable (10Base2), twisted pair (10BaseT), fiber optic (10BaseF), and broadband cable (10Broad36). The is designed so the communications protocols which operate above the Ethernet data link layer are implemented in software. This permits the user to choose between two* alternative communication protocols by downloading the Ethernet Controller with the applicable Communications Software: TCP/IP-Ethernet Communications Software - Communicate with host computers and/or MS-DOS or WIndows Programmer using proprietary SRTP over a 4-layer TCP/IP (Internet) protocol stack; requires either a Local or Network Factory LAN System Manager (GSM) for configuration and downloading of software. MMS-Ethernet Communications Software - Communicate with host computers and/or MS-DOS or Windows Programmer using MMS (Manufacturing Message Specification - ISO 9506) on a 7-layer OSI protocol stack; requires GSM for configuration and downloading of software. Figure 1 shows the general relationship between the, the local and network GSMs, and the MS-DOS or Windows Programming Software on Ethernet station. * A third option, SRTP communications software (IC641SWP711) supports only communications with MS-DOS or WIndows Programmers using SRTP over a 4-layer OSI protocol stack; this software does not require configuration and can be downloaded directly from the MS-DOS or Windows Programer.

3 2 Features of the The is a single-slot module that is inserted directly into the IC697 CPU rack. Connection to the Ethernet LAN is made via a transceiver cable to an external transceiver. The transceiver and cable are provided by the user. The transceiver is attached directly to the IEEE network cable. The Ethernet Interface operates at 10 Mbps on the Ethernet LAN. The uses three LEDs for indicating the status of the interface. A battery is provided to maintain the contents of Random Access Memory (RAM) over power outages. The provides basic functions in firmware or Read Only Memory (ROM). This firmware includes self-test diagnostics and special software that allows you to configure and test your interface in the PLC and on the Ethernet LAN. It also allows you to load the communications software into RAM either from the GSM (serially or over the network), or from an MS-DOS or Windows OSI-Ethernet Programmer station. The communications software is stored in RAM so you can upgrade communications software without replacing ROM chips. The battery maintains the contents of RAM over power outages. Soft Switches are used to tailor the to your application. The MS-DOS or Windows Configuration Software package is used to configure the in the IC697 PLC, and to set the soft switches for the. More detailed information about the Ethernet Controller, hardware installation, attachment to the Ethernet LAN, and Ethernet software follows this overview. For a complete description, refer to the User s Manual that applies to the software you choose to run on it. These related publications are listed on page 8. IEEE Media The can operate on any of the following media with the appropriate user-supplied transceiver cable and transceiver. IEEE specifies the definitive requirements of each medium. 10Base5 Coax: 10Base5 uses a 0.4 inch diameter 50-ohm coaxial cable. The maximum length of a cable segment (single span of cable) is 500 meters. The distance between any two stations must be a multiple of 2.5 meters. A maximum of 100 stations is allowed on a thickwire Ethernet segment. 10Base2 Coax: 10Base2 uses a 0.2 inch diameter 50-ohm coaxial cable. The maximum length of a thinwire cable segment is 185 meters. A maximum of 30 stations is allowed on a thinwire Ethernet segment. 10BaseT: 10BaseT uses a twisted pair cable of up to 100 meters in length between each node and a hub or repeater. Typical hubs or repeaters support 6 to 12 nodes connected in a star wiring topology. 10BaseF: 10BaseF has two variations that both use the same type of fiber optic cable: 10BaseFP can support up to 33 nodes at distances of up to 500 meters from a passive star; 10BaseFL supports up to 2000 meters between a node and a repeater (a multi-port repeater would thus constitute a star). Additionally, 10BaseFB provides a means of interconnecting (only) repeaters by up to 2000 meters of (the same) fiber optic cable. Note Various Ethernet baseband media can be interconnected by appropriate repeaters. Capabilities and limitations are defined in IEEE Chapter 13, System Considerations for Multi-Segment Networks. 10Broad36: 10Broad36 uses 75-ohm coaxial cable and CATV-like media components (taps, amplifiers, headend translators, etc.) to support hundreds of nodes at distances of up to 2800 meters. Broadband cannot be connected to baseband via repeaters. Broadband cable plant design and installation must be in accordance with IEEE and requires special expertise. GE Fanuc recommends you contract professional specialists for these services. Consult your GE Fanuc sales representative or field service office for help in identifying local specialists. 68-2

Open the front cover of the module. The battery is mounted in the holder, but is not connected to the board. (See Figure 2.) Connect the battery to either of the battery connectors on the card. Press down firmly to lock the battery connector in place. 4. Slide the into the slot for which it was configured in the system - normally the first available slot to the right of the CPU or Bus Transmitter Module (BTM). (See Figure 4. for the IC697 PLC rack layout) Press firmly to lock the board in place, but do not force the board Note The will not operate properly if there are empty slots to its left. P S GROUND WIRE C P U E T H E R N E T B T M CABLE a45349 TO Figure 4. IC697 PLC Rack Layout 5. Connect the free end of the ground wire (18 inch long green wire attached to the Ethernet module) to the ground lug at the side of the IC697 PLC rack. (See Figure 4.) Caution The ground wire must be securely fastened to the chassis of the IC697 PLC rack and the rack must be properly grounded. Failure to do so may cause improper operation of the LAN.

8 6. Connect the transceiver cable to the 15-pin AUI Port of the. The other end of the transceiver cable should be connected to an external transceiver which is attached to the IEEE network. Warning PLC power must be OFF when connecting or disconnecting the transceiver. Note Transceivers must be compatible and must have the SQE option Enabled. 7. Set the CPU Run/Stop switch to STOP. 8. Power up the PLC rack. Correct Results of Installation During Power-Up: The MODULE OK LED on the front of the will BLINK during power-up diagnostics, and continue to BLINK while waiting for configuration data from the CPU. After Power-Up: Once the has completed power-up diagnostics (about 15 seconds): The MODULE OK LED will stop blinking, and should remain ON. The ONLINE LED may be ON, OFF or BLINKING. The STATUS OK LED will normally be BLINKING (unless software was previously loaded), indicating that the Ethernet Interface needs to be loaded. If you get these indications, physical installation and power-up are complete. You may continue with Procedure 3 (or the next appropriate procedure) in Chapter 2 of the appropriate controller User s Manual. Corrective Actions MODULE OK OFF indicates a hardware fault, either in the or in the PLC, that prevents the from operating. Cycle power on the PLC to determine whether the fault is intermittent or a hard failure. 7 If MODULE OK remains OFF, examine the PLC Fault Table for diagnostic information and take appropriate action. See the IC697 Programmable Controller Installation and Operation Manual for information on the PLC Fault Table. For detailed troubleshooting information, refer to the applicable User s Manual. Configuring and Loading the As described earlier, the can be loaded with one of the alternative communications protocols. See Figure TCP/IP-Ethernet Communication Software. If the must support TCP/IP communications to MS-DOS or Windows TCP/IP-Ethernet Programming software to other IC69* PLCs, CIM- PLICITY products, or Host Communications Drivers applications, you must create a configuration file on the Factory LAN System Manager (GSM) and download that file together with the TCP/IP communications software. The GSM software runs on a separate computer. 2. MMS-Ethernet Communications Software. If the must support MMS communications, you must create a configuration file on the Factory LAN System Manager (GSM) and download it together with the MMS communications software. The GSM is a separate computer running GSM software. See the applicable user s manual for instructions on configuring and loading the. These operations are necessary before the LAN Interface can be used by your application. Station Management Software Operating a local area network entails certain LAN management activities. For the Factory LAN, this includes network performance measurement, fault diagnosis, configuration management, and downloading the appropriate configuration file and communication software to network nodes. Many features to support these activities are built directly into the. 68-7

9 8 Nonetheless, certain occasional maintenance activities require that the user provide an external computer, such as a properly equipped IBM-compatible personal computer. The software includes the Factory LAN System Manager (GSM) to run on this external computer. The GSM is used to store on disk and to download the communications software to the LAN Interface directly from the COM1 port on the GSM computer to the 9-pin serial port. The System Manager (GSM) also supports node configuration and downloading across the LAN from a centralized location. A network GSM computer must include an appropriate Ethernet Interface.
